Hongming Wang d8026347e5 chore: open-source restructure — rename dirs, remove internal files, scrub secrets
Renames:
- platform/ → workspace-server/ (Go module path stays as "platform" for
  external dep compat — will update after plugin module republish)
- workspace-template/ → workspace/

Removed (moved to separate repos or deleted):
- PLAN.md — internal roadmap (move to private project board)
- HANDOFF.md, AGENTS.md — one-time internal session docs
- .claude/ — gitignored entirely (local agent config)
- infra/cloudflare-worker/ → Molecule-AI/molecule-tenant-proxy
- org-templates/molecule-dev/ → standalone template repo
- .mcp-eval/ → molecule-mcp-server repo
- test-results/ — ephemeral, gitignored

Security scrubbing:
- Cloudflare account/zone/KV IDs → placeholders
- Real EC2 IPs → <EC2_IP> in all docs
- CF token prefix, Neon project ID, Fly app names → redacted
- Langfuse dev credentials → parameterized
- Personal runner username/machine name → generic

Community files:
- CONTRIBUTING.md — build, test, branch conventions
- CODE_OF_CONDUCT.md — Contributor Covenant 2.1

All Dockerfiles, CI workflows, docker-compose, railway.toml, render.yaml,
README, CLAUDE.md updated for new directory names.

-- #124 — delegation idempotency.
--
-- Adds an optional idempotency_key column on activity_logs so callers
-- (notably agents that may retry after a container-restart race) can
-- safely re-issue the same delegation without producing duplicate work.
--
-- The unique index is partial — only enforced for non-NULL keys so the
-- column is fully backwards compatible with existing rows.
ALTER TABLE activity_logs
ADD COLUMN IF NOT EXISTS idempotency_key TEXT;
CREATE UNIQUE INDEX IF NOT EXISTS activity_logs_idempotency_uniq
ON activity_logs (workspace_id, idempotency_key)
WHERE idempotency_key IS NOT NULL;
